Original application filedNovemher 7, 1911, Serial No. 658,985. Divided and this application filed January 3, 1912. Serial No. 669,271.

To all 'uihom it may concern Be it known that I, EDWARD E. GOLD,

' a citizen of the United States, residing in the borough of Manhattan, city, county,

and State of New York, have invented certainnew and useful Improvements in Steam-Heating Systems, of which'the following is a specification.

My invention relates to steam heating systems and is' particularly apphcable to heating systems for use m heatmg cars of railway trains. Itis a division of my application filed November'7, 1911, Serial No. 658,985.

An important object of the invention is to reduce the weight of the heating system installed in the car. Such heating system is maintained in the car throughout the entire year, and during a considerable part of the year itis not'required for heating .the car. But during all of this time it must be transported with the car as dead weight. The weight of such system whether in use or not furnishes a "large addition to the weight of the car, and its transportation is a subject of considerable expense to the railway companies.

. My invention therefore aims to reduce the weight of such steam heating system, and this I attain by a construction wherein a duplication of parts is avoided, and consequently the weight of the apparatus of the heating system is much lightened.

An object of my invention is also to provide a' steam heating system wherein the supply of heat radiated inay be decreased by reducing the extent of radiators in'use and thereby reducing the consumption of steam.

A further any radiator or radiators are so unused,

' there will be no back flow of steam thereto.

Further, to provide means controlled in' common by said radiatmgsystems when V acting as vapor systems for shutting ofi the Steam pply- In carryingmy invention into effect I provide a plurality of radiating systems in,

the car, either of. which may be discon nected independently of the others, and

which combined or singly are adapted to be operated as either pressure or vapor sys- .tems; and I provide means whereby when object is to provide that when such plurality of radiating systems are 013- I erated as vapor systems they are subject to a common control. In accordance with my lnvention a common supply pipe is provlded having an inlet valve, and each radiatlng system has an independent return PIPE. Each return pipe is adapted by adj'ustment to exhaust through its -independ-- the supply pipe.

may be embodied is illustrated in the accompanyin'g. drawings.

In the said drawings,Figure 1 is a plan view'of a steam heating system according to my invention, partly brokemthe parts beneath the floor of the car being shown in dotted lines; Fig. 2 is a cross-section there- Adesirable form in which my invention of on the line '22 in Fig. 1 looking toward the right; Fig. 3 is a view partly in elevation and partly in section of a common valve employed with said invention; Fig. 4

is a further view ofsaid valve and its connections partly in plan and partly in section; Fig. 5 is a view of the said valve partly in plan and partly in'section on the line 5-;') in Fig. 4; Fig. 6 is a view of the parts of the steam heating system below'the car floor taken on the line 66 in Fig. 2, illustrating the said parts partly in plan and partly in section. Fig. 7 .is a perspec-' tive View of a heating system having a different arrangement of radiators.

'I have illustrated my invention as applied to a steam heating system wherein steam. is supplied to the radiating systems located within the various cars from the train-pipe A which extends the length of steam therefrom to the supply pipe B which located *withinthe car. Each of the said the train,- and is supplied with steam from the locomotive boiler. Branches A are connected to the said supply pipe and conduct supplies steam to the radiating systems C C" systems has a. hand-controlled valve 0 by 'which steam may be SlilltOfiIflOlIl anyone of; the .said's'ystems. Asillustrated in Fig.

1, each car contains four of such steam heating systems, each of'which may be operated independently of the others, and they are illustrated as being divided so thattwo of such radiating systems are located upon Each of such radiillustrated as double each side of the car. ating systems is branched, having branches '0 0 each of which has a lower return pipe 0 0*. The employment of the double branched radiating pipe is not essential to .my invention and the said radiating pipe would be equally within my invention if a single steam pipe 0 and connected single return pipe 0 were used (Fig. 7). The extent of radiating surface may be increased when desiredby the 7 employment of such double branched radiators or by lateral branches H, as in Fig. 7 or by lateral loops illustrated in Fig. 1 and not lettered. Other means may also be employed to increase the radiatin surface, as for instance the coiled wire 71, (Fig. 1). My invention however is not concerned with such lateral branches or loops or wire coils and they form no part thereof.

The return pipes c c are each connected to return pipes J J which extend beneath the floor of the car and are there connected to a valve K. The said valve is illustrated in Figs. 3, 4; and 5. g It is provided with passages k k (Fig. 4) which extend from the said" return pipes J J to screened pipes Z leading to traps L. The said traps L are ordinary thermostatically controlled T-traps for disposing ofthe condensation water, and

- their construction forms no part of the present invention. Gravity traps M may well be sltuated in communication with eachfof the said passages 70 The valve K is provided with a central bore in which slides the valveproper, is? controlled by ahandle an by" as usual 1 extension handle-s i PortsJc" is connect the pasages k k with said central bore when the valve 70 is raised.

a It will be seen from the foregoing that when the valve is is closed and the steam escapes through'the passages k k of'the valve K and through the T-traps L, that the return pipes are entirely disconnected fromv I each other and are lndependent in their operation. Each T-trapcontains a thermostatic vessel Z which is partly filled .with'ai volatile fluid usually employed for that pur- I pose, such as alcohol, etc., and is adapted to? expand when steam pa'sses through, the re,-

--turn-pipe, and sea-t itself against the seat 1*,

. closing the pipe I; When the condensed water collects and cools the thermostat it I will contract'and withdraw from seat 1 under influence of spring Z and the pipe I will then be open and permit theescape of the condensed water. The systems will then operate as pressure syste The following means may be provided when it is desired that the system should being with the central bore when the valve is is raised and which when the system is op-,

erating as a pressure system, is closed by the valve 0 1 This outlet communicates with a drippipe or horn N, Fig. 5, which is open to operated as a vapor system :The valve K I ,is provided with a blow-ofl k communicatthe atmosphere at its lower end. When it is desired that the system operate as a vapor.

-.the same quickly responsive to changes in temperature. The drip pipe N has openings n by which'the thermostat is exposed to the temperature of the escaping fluid. within the drip pipe N. The upper end of this coil 0 is connected by tube 0 to a thermostatic chamber 0 having the usual diaphragm 0 which bears upon the head of valve stem 0*,

and closes the valve-P in the steam supply pipe A when the chamber o is expanded:

spring p maintains this'valve normally open, and the thermostat O operates to-close the valve against the pressure of this spring. It will now be seen that upon the raising of the valve [2 the condensed water and steam from the return pipes will be ,permittedto escape through ports k k which are then" uncovered by the valve 70 and to pass pipe N, and' 'that the temperature of the said escaping water or steam will affect the thermostat O' and through it control the valve P. Therefore when steam isescaping. from. hasa d-aetl mrip s' h o the common "outlet k? the-valve P will be closed, shutting off the supply of steam to each of the radia tors C C or to such of them as may be then in operation, 'and'when the temperature of the water of condensation passlng through "the drip N is sufliciently low 'to permit the contraction of the chamber 0 the spring 1) ply ofisteam will be permitted ,to flow into the radiators C0 The radiating systems C C have no communication with the atmospheres'ave through the traps Land M when the system is operating as a pressure svstem,;or-through-said traps and the drip N when the system is operating as a vapor.

Therefore should itbe desiredto reduce the supply of heat in the car, and forwill open the valve P and an additional supthis; purpose one of thevalves c be closed, steam will not have access to the said closed radiating system.
